The rolling bearing for a blade root includes an outer ring () and an inner ring (). An inner space () is defined between the inner surface () of the outer ring () and the outer surface () of the inner ring (). At a distal end (), the inner space () is closed off by a distal sealing system () between the outer ring and the inner ring. A system () for retaining the distal sealing system () includes a retaining body (), and a thread/tapping system provided on a peripheral assembly surface of the retaining body and on a peripheral surface of the facing inner or outer ring. The retaining body () is screwable into a retention position in which an axial abutment surface () of the retaining body forms an axial stop for the distal sealing system longitudinally (B), in the proximal-&#x3e;distal direction.
